I have an GMS.61 that I just bought.I broke it in and it idles and transits ok,but,if I put the nose up,It spit's and sputters and dies and if I put nose down, It revs up,up!!! Am I too rich or too lean? I read about problems with this engine's carb/rear seal,is this a problem with GMS engines and is it a piece of s*hit? It seems to be running fine,just this up/down nose problem,so help me out folks,PLEASE!!!
